An injection port is provided on the shaft, and the compost material is stirred while ejecting air from the injection port. The compost material can be agitated while rotating the stirring auger to move the compost material laterally and raising the compost material. In addition to being able to easily perform uniform agitation and maintaining air permeability of the raw materials, it is possible to easily secure aerobic conditions for composting by blowing air from the nozzles, and to easily reduce equipment costs and processing costs. .

[0004] In addition, an acid body is spouted from a spout of an auger shaft. Ammonia in a compost raw material that generates an offensive odor is neutralized with the constituents and remains in the compost.
Deodorization is performed, so that an expensive deodorizing device is not required, and a neutralized product of ammonia remains in the compost to become a fertilizer component, thereby easily preventing malodor and enhancing the effectiveness of the compost.

Further, a plurality of processing tanks are sequentially connected so as to be lower, and an outlet of a processing tank at a higher position is connected to an inlet of a processing tank at a lower position. The compost material can be sent to the processing tank on the lower position by stirring the compost material in the agitation auger, and the compost material transfer equipment between each processing tank is not required, and the compost maturity of the processing tank on the lower position is reduced. The compost material can be continuously fed into the processing tank at the highest position, and fully matured compost can be continuously sent out from the processing tank at the lowest position, making it easy to secure compost fermentation days and reduce the size of facilities. It is possible.

In addition, the agitator auger blades are formed in a sawtooth outer periphery, so that the agitator auger can improve the function of breaking down the compost material during lateral movement, reduce the lateral movement resistance of the agitator auger, and reduce the agitation of the agitator auger. It is possible to easily improve the compost raw material stirring efficiency and simplify the stirring auger mounting structure.

[0007] Further, the stirring auger blades are provided with projections to improve the function of breaking down the compost raw material of the stirring auger during lateral movement, reduce the lateral movement resistance of the stirring auger, and stir the compost raw material of the stirring auger. It is possible to easily improve the efficiency and simplify the mounting structure of the stirring auger.

Further, the agitating auger is configured to revolve around the vertical axis while rotating, thereby improving the function of breaking down the compost raw material of the agitating auger during lateral movement and reducing the lateral movement resistance of the agitating auger. In addition, it is possible to easily improve the stirring efficiency of the compost raw material of the stirring auger.

In addition, the present invention is configured such that livestock urine drainage, which is distinguished from compost raw materials such as livestock dung, is ejected from the nozzle, so that the livestock urine drainage discharged from the livestock barn can be treated simultaneously with the livestock dung composting. In addition, simplification and labor saving of wastewater treatment can be easily achieved.
